According to the correction tape disclosed in this document, a correction layer containing a pigment (particularly a white pigment) is applied to a normal lining, and then a correction layer containing a pigment other than the white pigment is applied. A contact adhesive layer is applied. This tape is particularly effective in that the correction layer can be applied without substantially reducing whiteness. This known tape can be advantageously used in a wound form wound on a hand-held "roller", so that the correction layer can be applied simply, quickly and uniformly to the substrate, thereby providing a text Typographical and typographical errors in drawings and drawings can be corrected. Characters can be written on the applied correction layer with a fountain pen or a ballpoint pen. According to the present inventors, in connection with such corrections, the pigments, such as letters covered by the tape, migrate to the surface of the applied coating layer, in particular due to the influence of moisture, so that the coated It has been found that characters and the like may become visible again.

It is characterized by showing anionicity. According to a preferred embodiment of the present invention, the thickness of the modifying layer is about 5 to 25 g / m 2 and the total thickness of the two layers is about 15 to 30 g / m 2 . Preferably, the thickness of the separate adhesive layer is from about 1 to 5 g / m 2, preferably about 2~4 g / m 2. Particularly good effects can be achieved when fine metal powder, particularly fine aminium metal powder, is present in the anionic correction layer and / or the adhesive layer. Preferably, the particulate metal powder is in the form of platelets. Aminium particles in platelet form have a thickness of about 3-10 μm and a diameter of about 4-17 μm. The dose of the fine metal powder is about 0.1 to 3.5% by weight, based on the dry particle layer. Particularly advantageous effects can be achieved when the anionic modifying layer is located between the cationic modifying layer and the adhesive layer. When the particulate metal powder is present in the adhesive layer, the order of the anionic and cationic modification layers is not important. According to one particularly advantageous embodiment of the invention, from the perspective of the lining, a cationic correction layer is applied first, followed by an adhesive anionic correction layer, with an additional pressure-sensitive adhesive layer. Not. Particularly preferably, the adhesive anionic modifying layer contains a particulate metal, preferably a particulate aminium.

の欄から4499頁の左側の欄まで。[0005] According to the basic idea of the present invention, the repair tape comprises a cationic repair layer and an additional anionic repair layer, regardless of the order of the layer structure. The terms "anionic" and "cationic" as used herein can be readily understood by those skilled in the art. The correction layer can suitably be produced using a binder dispersion, ie a dispersion comprising small solid polymer particles, especially a dispersion in aqueous form. Commercially available cationic / anionic aqueous dispersions include, for example, cationic aqueous dispersions Acronal® 280 KD (BASF AG), Butonal® LS 170 K (BASF AG), Jagotex® AL 2463 (Jaeger), cationic solution Worleecryl® (cationic acrylate alone solution, clear to milky solution, 7712W: 25% aqueous solution, 7712: 40% water / isopropanol (40/20) solution, in any case pH value about 5, Worlee Chemie GmbH, Hamburg), anionic aqueous dispersions Acronal® S 725 and S 726 (butyl acrylate / styrene copolymer, BASF AG), Acronal® V 205 (BASF AG) , Styrofan® D 422 and Propiofan® 6D (BASF AG). The activity described above depends on the particular surfactant used in the emulsion polymerization process. In the case of an anionic dispersion, as a stabilizer for emulsion polymerization, a sulfonate anionic group (—SO 3 − ), a sulfate anionic group (—OSO 3 − ) or a carboxylate anionic group (—COO − ) is used. An anionic surfactant containing a hydrophilic group or a polar group is used. These groups point outward from the dispersed polymer particles. In the case of a cationic dispersion, a cationic surfactant containing a quaternary ammonium ion (-N + (R 3 )) as a hydrophilic group is used in the emulsion polymerization method. All such information is necessary for a person skilled in the art to select suitable commercially available ionic aqueous dispersions to achieve the objects of the present invention. In this connection, reference is made to the following document: Dr. H. Stache "Tensid-

The above list of aqueous dispersions / water solutions is not exhaustive and the choice is not limited to the above list, and one skilled in the art can use other binders. This is because the essence of the invention does not exist in the type of binder but exclusively in the cationic or anionic character as the modifying layer. The binder concentration in the dispersion is also not limited. As a rough guide, the binder concentration is
It can be about 25-70% by weight, preferably about 40-60% by weight. The aqueous dispersion for forming the correction layer is preferably about 15-35 g / m 2 (dry weight), especially about 18-2

It can be either an ionic compound (eg, a completely water-soluble dye) or a non-ionic compound (eg, a disperse dye). Ionic dyes include anionic dyes and cationic dyes. Anionic dyes have negatively charged dye ions, while cationic dyes have positively charged dye ions, whereby
Generally, a distinction is made between acid dyes and basic dyes in advance. According to the present inventors, irrespective of the specific type of what is drawn, such as letters, that is, regardless of whether the drawn thing such as letters contains an anionic dye or a cationic dye, In the invention, it has been found that when covering a typographical error / misprint, etc., a troublesome pigment migration in which a pigment such as a dye penetrates the coating layer can be eliminated. When a character or the like includes an anionic dye, any dye migration can be blocked by the cationic correction layer in the correction tape of the present invention. When a cationic dye is included, this blocking effect is achieved by the anionic coating layer, for example, by binding the cationic dye to the anionic layer. Note that a dye such as a dye does not penetrate the polymer itself, but can pass through micropores existing in the correction layer. As a dye, such as a dye, moves through such pores, the dye automatically contacts the outwardly facing surface-active moieties on the polymer particle surface and is captured by the corresponding interaction.

【００１７】 実施例1の分散体に代えて、この分散体を用いてアニオン性修正層を形成した 。この組成は、粘着性を示すように設計したため、実施例1のような感圧型接着 剤層を形成することは、不要である。分散体は、用量10 g/m2で適用した。An anionic modifying layer was formed using this dispersion instead of the dispersion of Example 1. Since this composition was designed to exhibit tackiness, it was unnecessary to form a pressure-sensitive adhesive layer as in Example 1. Dispersion was applied at a dose 10 g / m 2.
